As the US space agency misses its launch window for the second month, smaller firms continue work on their partsIt was shaping up into another ordinary day at the Colorado headquarters of the small space startup Lunar Outpost last Friday when chief executive Justin Cyrus learned of a surprise press conference called by Jared Isaacman, the new administrator of Nasa.Cyrus's company epitomises the many private contractors of the space agency working on a myriad of projects crucial to the Artemis program that seeks to return humans to the moon, so anything Isaacman had to say about it was naturally of interest to him.

In search of a new adventure, Craig Munns went back to school. Now, at 65, he spends his days examining long-vanished life formsCraig Munns has a large model of a T rex on his desk. He got it with a magazine subscription two decades ago. One day, a few years ago, he was sitting in his study, which was dense with books and yellow sticky notes and posters charting evolution from single cells upward, and he thought, What am I going to do next in my life?" And his eyes lit upon the T rex.Munns had recently taken on a job at the public library in Canberra, but it had always rankled with him that he had not studied for a degree, starting instead as an electronics trainee after he left school in Sydney, Australia. So he decided to enrol as a part-time student. He graduated at 62, with honours in palaeontology from the University of New England in Armidale, NSW. Continue reading...

Constellation of Cancer is not easy to locate but reward is the star cluster M44 at its centreThe constellation of Cancer, the crab, is now high in the southern sky during the late evening. While not the easiest constellation to locate because it does not contain any truly bright stars, it does offer a reward for patient observation: the star cluster M44, also known as the beehive cluster.Begin by finding Cancer. It is located halfway between the constellations of Gemini, the twins, and Leo, the lion. The chart shows the view looking south from London at 10pm UK time on 9 March. Continue reading...

Jane Logan pays tribute to her late husband's lifelong passion for classifying organismsMy late husband, Niall Logan, professor of bacterial systematics at Glasgow Caledonian University, would have been astonished that his lifelong field of academic study, taxonomy, in his case the genus Bacillus, would merit an entire article in the Guardian (I love midges because I know what their hearts look like'': is the passion for taxonomy in danger of dying out?, 2 March). It is certainly not sexy science, and chasing funding for research projects was always tiresome.However, how about mentioning some of the spinoffs of his research, which many would have thought dry in the extreme? He spent time in the Antarctic researching Bacillus species found in geothermal soils, his expertise was sought when old tannery sites were to be redeveloped to exclude presence of anthrax, and the food industry needed his expertise when investigating food spoilage. His knowledge was valued and his guest lectures were welcomed worldwide. Continue reading...

Researchers who listen for signs of non-human life say signals can slip below detection thresholds, even if it's there'Earth's leading alien hunters believe extraterrestrials could be out there, they're just having a hard time getting through to us because it's stormy in space.Reminiscent of ET's struggles to phone home" in Steven Spielberg's 1982 blockbuster movie, new research by the Silicon Valley-based SETI Institute (search for extraterrestrial intelligence) suggests tempestuous space weather makes radio signals from the distant cosmos harder to detect.

It's not a question of if, but when, another pandemic hits Britain. We owe it to all those who suffered to make sure mistakes are not repeatedWhat makes the independent inquiry set up to examine the UK's response to, and the impact of, the Covid-19 pandemic unlike any other in British history is that we are not examining something that affected one specific group of people. The chair, Heather Hallett, and her team have investigated a virus that swept the land and affected every single person in the UK at a profound and long-lasting level.We have published two inquiry reports, with eight more to come. Each is full of valuable insight, carefully considered conclusions and recommendations about what must now change to ensure we are better prepared for next time. Continue reading...

The conflict in the Middle East has sent energy prices soaring, and for countries that import a high proportion of their fuel, it's a reminder of the perils of energy dependence. As the recipient of almost 90% of Iran's crude oil, China knows this only too well. Which partly explains why the country spent the last decade heavily investing in clean power.To find out what else could be driving the strategy, Madeleine Finlay speaks to senior China correspondent Amy Hawkins.And energy correspondent Jillian Ambrose reflects on how China's ambitions could affect the rest of the worldSupport the Guardian: theguardian.com/sciencepod Continue reading...

Four cemetery workers dug up and moved more than 100 bodies to resell the burial plots nearly 20 years agoIt was a particularly heinous crime. Four workers at a cemetery near Chicago dug up more than 100 bodies and dumped the remains elsewhere in the grounds, in order to resell the burial plots for profit.Now, nearly two decades after the scandal broke at Burr Oak cemetery in Alsip, Illinois, scientists have released details of how a tiny clump of moss became crucial forensic evidence that helped convict the grave robbers.

Scientists are calling loss of biodiversity the homogenocene', where niche species are pushed out by generalists like pigeons and ratsPlants and animals are disappearing at an alarming rate across the planet, with some estimates suggesting a loss of up to 150 species every day. Meanwhile, the versatile species that thrive alongside humans, such as pigeons, rats and cockroaches, expand to fill the vacant gaps. Some scientists are calling this loss of biodiversity the homogenocene": the era when the world's wildlife became more samey.It started during the last ice age, when humans hunted large mammals such as the mammoth to extinction, and has continued to the present day as land is cleared to make way for fields, farms and cities. Specialist creatures that exploit a particular niche - such as the flightless Fijian bar-winged rail - have been pushed out by adaptable generalists, like mongooses, brought to Fiji by humans in the 1800s. More recently the homogenocene has hit the oceans, with warmer waters devastating coral reefs for example. Continue reading...

Storeton Wood, Wirral: Two centuries ago, this area teemed with workmen busying building Liverpool; more than 200m years ago very different creatures roamed hereAt last, the sun shone after weeks of rain. While the distant Welsh hills were draped in snow, here on the Wirral it was dry and bright. Storeton Wood is a secondary woodland of oak, beech and silver birch, and formerly a quarry. Below, a cuprous layer of leaf has protected the soil from the recent assault of raindrops. Fallen limbs were a feast of fungi; in places, creamy white Storeton sandstone peeked through like discarded vertebrae. Great spotted woodpeckers drummed.Standing by the remnant of George Stephenson's quarry track, I envisaged the 1838 scene: workmen busy extracting sandstone, sudden shouts of discovery and confusion, handprints in the rock. They thought they were the signs of people perished in Noah's flood. Victorian scientists later confirmed that they were footprints of a crocodile-like creature named Chirotherium storetonense (Chirotherium meaning hand beast") dating from Triassic times, 240m summers ago.

In the past three months, Donald Trump's White House has reportedly used AI twice to effect regime change - once in its capture of Venezuela's president, Nicolas Maduro, and more recently to help plan the strikes that killed Iran's supreme leader, Ayatollah Ali Khamenei.The most recent strikes coincided with the end of the Pentagon's relationship with the AI company Anthropic over concerns its AI tool Claude was being used for purposes the company had explicitly prohibited. The government swiftly signed a new contract with Open AI.To find out what this means for the use of AI in forthcoming conflicts, Madeleine Finlay speaks to technology journalist Chris Stokel-Walker. He explains why he thinks this moment represents a dangerous turning point.Trump is using AI to fight his wars - this is a dangerous turning pointSupport the Guardian: theguardian.com/sciencepod Continue reading...

A magician reveals his visual tricksEarlier today I posted five optical illusions by Olivier Redon, a French-American inventor. Here they are again - with demonstrations of how he created the effects.Three of the images are inspired by the Necker cube, a two-dimensional drawing of a cube that can be understood in two ways: either with the bottom left face at the front, or the top right face at the front. Once your eyes settle on one interpretation, it is hard to see the other. Continue reading...

Insect taxonomist Art Borkent has described and named more than 300 species of midges but fears his field of science is dying out, despite millions of insects, fungi and other organisms waiting to be discoveredOnce Art Borkent starts speaking about biting midges, he rarely pauses for breath. Holding up a picture of a gnat trapped in amber from the time of the dinosaurs, the 72-year-old taxonomist explains that there are more than 6,000 ceratopogonidae species known to science. He has described and named more than 300 midges, mostly from his favourite family of flies. Some specialise in sucking blood from mammals, reptiles, other insects and even fish, often using the CO from their host's breath to locate their target, he says. Tens of thousands remain a mystery to science, waiting to be discovered.But to Borkent's knowledge, nobody will continue his life's work of identifying and studying this group of flies once he has gone.

When I found out my father had been adopted, I was curious to know more about his side of the family. Nothing could have prepared me for what I would discover ...Above my grandma's bed hung a framed blackand-white photograph of my dad. As asmall child I quietly admired it; his luminous eyes, dark hair and gentle smile. He embodied a tender yet spirited early adulthood, staring into the future. Handsome and seeking.As I grew older, I would discover that it was not, in fact, a photograph of my dad but of a man called ElvisPresley. Apparently he was very famous. My grandma had been a lifelong fan. My parents laughed - an adorable mistake - but I felt a hot pulse of humiliation. Continue reading...

The president's cuts have defunded and alienated thousands of American scientists. Europe can benefit, if it makes the right offerDonald Trump has spent much of his second term at war with science and scientists. He is cutting staff at institutions such as the Environmental Protection Agency (EPA) by a third, and has cancelled or frozen up to 8,000 federal research grants. This hasn't just hurt individual research programmes, it has damaged America's credibility as a reliable partner in the scientific community. It is not surprising that many researchers - one poll last year by the journal Nature gave the number of 75% - say they are considering leaving the US entirely.However, it is one thing to express dissatisfaction, and quite another to up sticks and leave. If the UK and EU want to attract elite scientific talent, their approach must be twofold: appealing directly to scientists concerned with political interference in their research, and offering stable, ringfenced money.Do you have an opinion on the issues raised in this article?

Scientists say DNA evidence indicates male Neanderthals and human females interbred more often than oppositeTens of thousands of years ago, as modern humans migrated into northerly territories inhabited by our ancient cousins, the Neanderthals, the two species met - and sometimes mated.Now, genetic evidence has revealed a striking imbalance in these prehistoric trysts, suggesting that interbreeding was mostly between male Neanderthals and female humans.

Falling volcanic ash has for years been viewed as a nuisance. But a Sicilian project has discovered its agricultural potential and wants to spread the wordIn the Sicilian town of Giarre overlooking Mount Etna, Andrea Passanisi, a tropical and citrus fruits producer, uses an unusual fertiliser on his 100-hectare (247-acre) stretch of land: volcano ash.Like hundreds of farmers and citizens of rural towns perched on the slopes of Europe's highest and most active volcano, the 41-year-old's family has had to deal with the nuisance of falling volcanic ash for generations. But it is only in recent years that the quantity of ash has become so excessive that it required an alternative approach. Continue reading...

Orforglipron led to greater weight loss than semaglutide tablets and could offer more effective oral alternative to jabsA new daily pill could be a more effective GLP-1 tablet for weight loss, according to a clinical trial that may pave the way for an improved non-injection alternative to Wegovy and Mounjaro.The drug, called orforglipron and manufactured by Eli Lilly, is prescribed for type 2 diabetes and targets the same GLP-1 receptors as oral semaglutide. Like semaglutide, it lowers blood sugar levels, slows digestion and suppresses appetite. Unlike semaglutide tablets, it does not need to be taken on an empty stomach. Continue reading...

Sunrise is a majestic spectacle - but we should be grateful for the miles of vacuum between us and the starDawn on a still morning is a majestic spectacle, as sunlight spills silently across the landscape and the Earth gradually emerges from darkness. Sunrise has inspired countless pieces of music striving to express this soundless experience in audible form. But if we could actually hear the sun, it would be deafening.The sun is a giant nuclear fusion reactor, converting hydrogen into helium and releasing massive amounts of energy in the form of heat - and sound. Sound is essentially vibration and needs a medium to travel through. Continue reading...

Since the 1960s, global GDP has been rapidly rising and living standards have reached record highs. But something else has been rocketing up too - carbon emissions. For years, scientists and economists have been asking: is it possible to grow without heating and polluting the Earth? And as the climate becomes more unstable, the issue is only becoming more urgent. Madeleine Finlay hears from two economists arguing for a change in how we measure a country's success. Nick Stern is professor of economics and government at the London School of Economics and an advocate of green growth, an approach to growth that prioritises green industry. Jason Hickel is a political economist and professor at the Autonomous University of Barcelona who advocates degrowth, shrinking parts of the economy that do not advance our social and ecological goals.Catch up with all the pieces in the Beyond Growth seriesSupport the Guardian: theguardian.com/sciencepod Continue reading...

It makes rejection, teasing or criticism feel unbearable, often prompting a strong physical reaction. Sufferers describe life with a condition that is only just starting to be understoodJenna Turnbull's chest is tightening. The 36-year-old civil servant, who lives in Cardiff, can picture herself as she speaks: an 11-year-old in her PE kit waiting with the other kids for her lesson to start. We were outside by the courts waiting to play netball," she says. Somebody commented that I had hairy arms, one of the boys." Her voice wobbles. The incident was clearly juvenile; rationally, she knows that. Yet 25 years on, her embarrassment is still visceral, with the power to cause instant physical discomfort.She searches for another example of her acute reaction to teasing and recalls a trip to the pub with her friends six years ago. Amid the loud conversation and laughter, a quip was made in the group about her being untidy at home. Or that's how she perceived it. About me not keeping on top of the house," she recalls. The person was having a laugh. It was just something that was said off the cuff." Yet while the memory and detail is hazy, the shame she feels about it is not. That comment still haunts me," she says. After that pub outing, she started cleaning her house obsessively - to such an extreme that it became one of the symptoms leading to her diagnosis of obsessive compulsive disorder (OCD). I've been known to spend four or five hours cleaning my bathroom," she says. Continue reading...

Researchers discover rare periods of a few thousands years when climate unexpectedly awoke from slumberDuring the "snowball Earth" period about 700m years ago, Earth's climate shut down. The planet was encased in ice and insulated from seasonal variations: spring, summer, autumn and winter all stopped. Or at least that was the theory.Recent examination of some ancient rocks from the west coast of Scotland has now overturned that thinking, suggesting there were periods during snowball Earth when the climate woke up.

Wold Newton, East Yorkshire: On a dreary day in a nondescript field, I visit the site where a 4.56 billion-year-old bit of space rock came to EarthOn a low rise, beyond a screen of trees, behind a small holiday park in the Yorkshire Wolds, a brick obelisk stands incongruously at the edge of an otherwise nondescript field. It bears a plaque inscribed as follows: Here, on this spot, Decr. 13th, 1795 / fell from the Atmosphere AN EXTRAORDINARY STONE / In breadth 28 inches / Inlength 36 inches..."The words are carved in a variety of enthusiastic fonts, with the opening Here" given particularly earnest flourish. The extraordinary,extraterrestrial stone in question is the Wold Cottage meteorite, the first from anywhere to be widely recognised as a rock from outer space. After a 4.56bn-year journey, it now rests in the Treasures Gallery of the NaturalHistory Museum. Continue reading...
